CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 304,335, dated September 2, 1884.

Application filed November 30,4883.

To aZZ whom it may concern:

Be it known that I, CARSON A. lVIASTER- SON, a resident of the city of Decatur, and State of Illinois, have invented certain new and useful Improvements in Corn-Planters, of which the following is a specification.

My invention relates, mainly, to the reeling device for the check-row wire, to the device used to raise and depress the runners, and to the device used to drop the corn,'all of which will be hereinafter set forth in detail and specifically claimed.

In the drawings accompanying and forming a part of this specification, Figure 1 is an end vicw'of the check-row-wire reel, and Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation of the rear extremity of a cornplanter, showing the arrangement of the reel with relation thereto. Fig. 4 shows a preferred construction of the reel-shaft crank in side elevation, and Fig.5 is an end view of the same. Fig. 6 is a plan of a corn-planter, showing the position of my devices thereon. Fig. 7 shows the lever and ratchet used to elevate and depress the runners, and Fig. Sshows the device used to connect the lever with the frame of the runners. Fig. 9 is a side elevation of the seat-support and the treadle used to operate the wire-reel, showing transverse parts in section on dotted line mm, Fig. 3. Fig. 10 is a vertical section of the seed box and dropping mechanism on dotted line 2 c, Fig. 6. Fig. 11 is a face view of the drop-wheel, showing the general arrangement of the cut-off with reference thereto; and Fig. 12 is a central vertical section of Fig. 11 011 a line parallel with the ends thereof.

a is a friction-pulley provided with a beveled edge, as shown.

bis the reel, which is constructed in a form not materially different from that in general use.

0 is a tubular shaft, on which both reel and pulley are rigid.

(Z shows the wire in position on the reel.

6 represents scrapers for cleaning the wheels. They are secured to shaft 9 by means of setscrews f. Reel-shaft 9 forms a crank at 0,- and I prefer to construct this crank separately, and in substantially the form shown in Figs. 4 and 5.

h represents an arm rigidly attached to shaft (No model.)

9, and provided with a rod, i, that connects witha treaclle; by means of which said shaft 9 is operated.

Z Zare brackets that support shaft g.

mis a bar of the planter-frame, to which brackets Z Z are secured.

per bearing being square, while the lower bearing is circular.

The above-mentioned device not only adapts itself to the square end of g and to the round end of the extension on which the reel operates, but also furnishes a bearing at 0 for brackets Z Z. The rims 0 0 prevent longitudinal misplacement of the crank in the brackets but, if preferred, the inner rims may be dispensed with and the outer rims of each crank be relied on to maintain the correct position. 'lVhen the inner rims are dispensed with, the cranks can be readily slipped into position in the brackets; but in that case said cranks must be secured to the shaft 9.

1) represents alever provided with a sliding catch-rod, p, which is held in contact with segmental ratchet q by means of spring 1)", and which is peculiar only in terminating at right angles to its general direction in such a position relative to the lever-handle that the pressure of the hand in operation will tend directly to raise the catch-rod from contact with the ratchet, (see p.)

The lever 19, above described, is rigid on shaft 1*, and arm tis also rigid on the same shaft. Then, arm t being connected with the frame D of the runners, it follows that a forward throw of the lever p will depress said;

the vertical chain, suspended as shown, combine to furnish arm t with the independent motion necessary to its perfect operation.

w w are the seed-boxes.

z is the check-row rod, which is intermittently rotated in one direction by the action of the check-row wire, and which is connected with the drop-plates of the seed-boxes by suitable gearing, x.

y y show the runners of the planter, con structed in the customary manner.

B (l are transverse bars of the planter-frame, one acting as an axle for the wheels A A and the other as a support for the seed-boxes.

- Brackets s s and ratchet q furnish bearings for shaft 1', and treadle a is loosely journaled on said shaft at a".

Fig. 9shows the arrangement of treadlo a with relation to the reel-shaft g, and also the construction of the seat-support k k.

1 in Figs. 10, 11, and 12 represents a vertical disk provided with an annular rim or projection, and connected by suitable gearing with the check-row bar. The annular rim of disk 1 is perforated at regular intervals, and is so located in the bottom of the seed-box that the grain is readily admitted through its open face.

A peripheral casing prevents the corn from passing through the perforations of the rim, except at one point at the lowest extremity of the casing, as indicated at 6 in Fig. 10, and this point is coveredby a cut-off, 2 3, as shown. The perforations 6 are to be of the correct size to receive the right number of grains for a hill, and to this end the thickness of the rim may be varied when necessary. The cut-off consists in two parts, one of which, 3, is the actual cut-off, while the other, 4, is a casing for the rear end of 3 and its operating spring. The cut-off 3 consists in a top casing of substantiallythe configuration shown in Fig. 12, and which, with its two side casings, forms a receptacle for the corn that forces its way into the same. Casing 2 is of the same width as the rim of the drop-plate, and entirely occupies the space therein indicated by its outline in Fig. 11. This casing, which is rigid with the downward extension of the seed-box, furnishes a pivotal bearing for cut-off 3 and a place for the unobstructed operation of projection at and spring 5. The seed-boxes w, as shown in Fig. 10, terminate in the interior of the annular drop-plates, thus insuring a constant supply of grain thereto. In operation, the drop-plates are rotated in a direction op-. posed to the projection of the cut-off, and the corn contained in the perforations of the rim is carried under said cut-off and permitted to escape through the opening indicated in Fig. 10. The pivotal adjustment of the cut-off is to avoid crushing grains that from their oblique position on the edges of the perforations, or from other reasons, have a tendency to force their way under said cut-off, and the hollow, receptacle therein is to receive such grains and permit their subsequentescape without interfering with the effectiveness ofthe drop.

The reel is operated by pressing on treadle u a, which, through rod 2' and arm h, causes the shaft 9 to partially'rotate and carry the edge of pulley or against the planter-wheel A.

The operation above described is carried into effect whether it is required to wind up the wire or regulate the tension in laying out the same, only that more pressure is ordinarily required in the former process.

The object of the beveled edges of pulley a is to enable the said pulley to'forcc its way through the dirt which scrapers 0 may not be able to remove, thereby insuring constant and direct contact with the metallic surface of the planter-wheel, and consequently a competent supply of friction. "V here friction pulleys with even a moderately-broad surface are used on planter-wheels, their tendency is to pack the dirt firmly against said wheel and form an anti-friction surface on which the pulley will slip.

The arrangement of my reel and pulley on a tubular shaft makes practical their ready attachment to all arrangements of shafts, no matter by what means leverage is brought to bear thereon.

I am aware of the concave-faced pulley used to impart the motion of the planter-wheel to to a check-row-wire reel that is shown in patent to G. D. Haworth, No. 277,030, May 8, 1883. I am aware, also, of the fact that friction-pulleys and check-row wire reels have been mounted on the same shaft, as disclosed in Patents No. 286,218, October 9, 1883, to Geo. W. and F. P. Murphey, and No. 262,608, Au-

gust 15, 1882, to Andrew M. Munson ,and thcrcfore lay no broad claim to the same.

I claim 1. The combination, with a check-row-wirc reel adapted to be operated by friction from the planter-wheel, of a friction-pulley rigid with said reel, and beveled to an'edge on its periphery, as and for the purpose set forth.

2. The combination, in a device for elevatin g and depressing the runners ofa coi-irplanter, of a bent lever, 12 s t, a shaft, v, pivoted in a vertical frame, 22', and provided with lat eral arms 21, and a chain, 1), connected with the arms 1;, and adapted to furnish a point of attachment for the bent lever '15, as and for the purposeset forth. v

3. The combination, with a vertically-rotating annular drop-plate provided with perforations to measure and discharge the grain, of cut-ofi 3, adapted to be operated by a spring, 5, in casing 2, and provided with a cavity to receive and permit the escape of grains that force their way under said cut-off, as set forth.

4. The combination, in a detachable reel for check-row wire, of reel 1), tubular shaft 0, and friction-pulley a, as shown and described.
